Lots of names, very little in the way of solutions. Clemmey isn't going to be there in a long, long time and pitcher success rate is very low. The rest are either some distance away or a few upgrades away from being BOR options. There's not one name you mentioned who you could throw in MLB today and expect to hold their own. Dion and Cantillo are the closest but you're either looking at questionable stuff or what's looking like a reliever's command. You could throw Leftwich in there too. None of them actually give me any kind of confidence.
You'd need a lot more of these kinds of names for the odds to work in our favor. I remember just last year there was discussion here about how somehow Curry, Pilkington, Battenfield etc. were good enough that we could afford to trade away some live arms for them. Give me a break lol. And the recent promotions are just filling in holes left or soon to be left by guys like Bieber, Plesac, and Quantrill. We're not net adding.
